Share on social media

Want to learn about converting audio to text? That's exactly what we're covering in this quick guide to audio transcription!

Transcribing audio files can help you capture key information, create subtitles, or repurpose content. However, transcribing can be time-consuming and tedious if done manually. Luckily, there's a simple way to transcribe your audio files in just three easy steps using Castmagic transcription software.

The process involves selecting and uploading your audio file, initiating the automatic transcription, and then making any final edits like adding speaker labels. Using transcription software saves significant time and effort compared to typing out an audio file from scratch. Let's dive into the specifics of how to quickly and easily convert your audio to text using Castmagic.

Step 1: Choose and Upload Your Audio File

The first step is to select the audio file you'd like to transcribe. Castmagic is a highly recommended automatic transcription tool that supports a variety of common audio formats, including .m4a, .mp3, .mp4, .wav, .aac, and .mov. Alternatively you can even transcribe video files found on platforms such as YouTube, Vimeo, TikTok, and Instagram, or add an RSS feed to quickly import recordings. Yep, you read that correctly. Castmagic can convert audio from video URLs and from video files as well.

To get started, create an account on Castmagic if you don't already have one. Then, in your dashboard click the “Import audio or video” button. Add your video’s URL and click “Submit” or drag and drop your video files into the “Upload Audio” section. 

Step 2: Transcribe Your Audio File  

Once your audio file is uploaded, you're ready to start the automatic transcription. Add a number and title to find it quickly in your dashboard, then click “Save Recording.”.

Castmagic will then analyze the audio using advanced speech recognition technology and generate a text transcript. In a few seconds, you will have a transcript ready to review. 

Step 3: Add Speakers and Finalize Your Transcript

After Castmagic has transcribed your audio, you'll have the chance to review and edit the automatically generated transcript. This is an important step to ensure your final transcript is as accurate and readable as possible.

First, check that speakers are properly labeled throughout the transcript. Clear speaker labels make it easy to follow the conversation. Castmagic allows you to add speaker names by clicking "Speaker A," "Speaker B," etc. from the transcript. From there you can add the speaker’s name and their role (i.e. host or guest).

Finally, read through the transcript and make any necessary corrections by clicking “Edit Transcript.”

Castmagic's transcription technology is usually pretty accurate, but there may still be a few errors. This is especially true if the audio quality was poor or there were overlapping speakers. You can quickly fix any issues directly in the Castmagic editor.

The Old School Way - Transcribing Audio Manually

Before transcription software became widely available, the only way to convert audio to text was through manual audio transcription either on your own or by hiring a transcription service. This painstaking process involves carefully listening to an audio recording and typing out the content word-for-word. While much more time-consuming than using automated transcription, manually transcribing can still be necessary in certain situations. Here are the three main steps:

Step 1: Do an Initial Listen and Note Trouble Spots

Begin by listening through the entire audio file from start to finish. As you listen, make note of any timestamps where the audio is difficult to make out due to background noise, overlapping speakers, accents, etc. Identifying these trouble spots upfront will help you be prepared when you start transcribing.

Step 2: Listen Again Slowly and Transcribe

Once you've made your way through the audio initially, go back to the start. This time, listen very slowly and deliberately, transcribing the content into a text document. Be sure to include precise speaker labels, timestamps, and any other necessary annotations.

When you reach one of the trouble spots you noted in Step 1, don't be afraid to replay that section multiple times until you're confident you have an accurate transcription. Using a transcription player that allows you to skip back can be very helpful.

Step 3: Review and Verify the Transcript 

After you've transcribed the entire audio file, go through your transcript carefully one more time to verify its accuracy. Listen to the original audio again while reading your transcript to check for any missed words or incorrect phrases. It's easy for minor errors to slip through, even when you're being diligent.

This review process is arguably the most important part of manual transcription. A final polish helps ensure your transcript truly captures the audio content with precision.

The Downside of Manual Transcription

While listening and typing out audio manually can produce extremely accurate transcripts, this traditional method has one major drawback: it is excruciatingly slow. Transcribing even a 30-minute audio file could take 3-5 hours of intense focus.

For situations where you need a quick turnaround or are working with large volumes of audio content, manual transcription simply isn't feasible. This is where leveraging automated transcription software like Castmagic can save you hours of valuable time.

Word of Caution - Don't Use Free Transcription Software

While the lure of free transcription tools can be tempting, it's important to avoid these when working with sensitive or proprietary audio content. Free transcription software and web apps typically have poor accuracy rates and lack critical security features to protect your files.

Most free transcription offerings make you upload your private audio recordings to their servers for processing. This raises major privacy and data security concerns. You have no way to verify what actually happens to your files or guarantee they won't be accessed by unauthorized parties.

Paid transcription services like Castmagic operate on a secure, encrypted platform where your data privacy is ensured. Your audio never leaves your possession until you choose to upload it directly to Castmagic's servers for transcription.

Additionally, free transcription software is notoriously inaccurate compared to premium tools that use more advanced speech recognition technology. This means you'll spend far more time cleaning up transcription errors if you go the free route - likely negating any time "savings."

For personal transcription needs where privacy isn't a major factor, free tools may suffice. But when working with confidential meetings, interviews, or any proprietary information, it's absolutely essential to use a reputable, secure transcription service. Don't cut corners that could compromise your data security or result in an unusable transcript.

Investing in a paid transcription solution like Castmagic provides peace of mind that your recordings are kept private while also delivering a fast, highly accurate transcript. This professional-grade approach ensures you can maximize the value of transcribing audio files. 

You’re Ready to Be a Transcribing Aficionado!

To recap, there are two main methods for transcribing audio files - automated transcription software like Castmagic, or manual transcription by carefully listening and typing out the content. 

The automated approach with Castmagic is a straightforward three-step process: 1) Upload your audio file, 2) Initiate the automatic transcription, and 3) Review and edit the transcript, adding speaker labels as needed. This method is significantly faster than manual transcription.

However, manual transcription can still be useful in situations where you need the highest possible accuracy. It involves a straightforward three-step process as well. 1) Listening through the audio multiple times - first to identify trouble spots, then to slowly transcribe while replaying sections as needed, and finally to verify the completed transcript against the original recording.

Whichever transcription method you choose - whether it be using transcription software, or handling the transcription process manually, the end result is an accurate text version of your audio content that unlocks a variety of benefits. Transcripts make audio and video recordings more accessible, allow people to quickly skim the key points, and can help with SEO for those assets. You can also easily repurpose transcripts into articles, blog posts, training materials or eBooks.

Whether you have conference audio files, legal files, podcast episodes that need transcribing and value a fast turnaround, give Castmagic's automated transcription a try. You'll be amazed at how much time you save compared to manual transcription. Click here to start a free trial of Castmagic today.
